Engine bolt up 54 Chry NY ?

[Frank Wilkie]

I have a chance to get a 1955 Chrysler New Yorker  engine & transmission in order to have a spare but would it bolt up the same way in my 1954 New Yorker?    Any differrences?

My book shows that 54s came in both short and extended blocks.

Also the part numbers for the blocks 54 and 55 are different.

Will it bolt up? I would think so if both are short but there must be some differences.

 

A quick comparison shows different dampener,  Several different crankshaft numbers,  Heads late 53 and 54 same (appears that exhaust manifolds and 2bbl intakes  follow this as well),  Distributor different, fuel pump same,  oil pan same,

Motor mount brackets are the same, but showing different insulators.

If there are any parts in particular you want me to look up let me know.

Extended bellhousing on the back of the block fits Fluid Drive and Fluid Torque Drive transmissions. When they went to the Powerflite automatic in 1954 they changed to a conventional block without the bellhousing. It is easy to see the difference, and why they will not interchange.

So, your 54 and the 55 should be alike and interchangeable.
